Yes, the default offset is OK. Actually I should try which one of the "offsets" is actually mandatory, because them being mandatory makes no sense (but nothing on Android does, tbh). Also, enabling NFS client is easy enough: just copy nfs.ko from rootfs (or enable as builtin if building your own kernel). Busybox's default mount is enough to connect to NFS as long as you pass -o nolock to disable dependency on localhost lockd/portmapper. Seems like tis may be similar to this other, freely licensed module. Maybe you should open a new thread and try to figure out how to make that module work. BTW. Another disappointment is that the stock kernel is tainted propietary by this module.
